<P>PROBLEM TO BE SOLVED: To provide an image processor, an image processing method and an image processing program in which development can be accelerated while reducing the cost and a pulse width modulated signal can be taken in directly and confirmed. <P>SOLUTION: The image processor comprises a general purpose computer 24, a clock generator 407, and a PWM demodulating section 405 wherein the PWM demodulating section 405 demodulates pulse width modulated image data delivered from a printer controller 100 connected through an interface. The general purpose computer 24 reads out a pattern image for detecting positional shift from the image data, detects the frequency shift between a video clock signal generated from the printer controller 100 and a clock signal generated from the clock generator 407, calculates back a correction amount from the detected shift, and then delivers it as the correction value of video clock signal of each color to the printer controller 100. <P>COPYRIGHT: (C)2003,JPO |
